Reactions of the (100) surfaces of Ge and Si with organic molecules have been generally understood within the concept of “dimers” formed by the 2×1 surface reconstruction. For example, it was recently discovered that adsorption of tert-butyl isocyanide (TBIC) on Ge(100)-2×1 occurs through a dative bonding configuration through the isocyanide carbon atom.[1] Here, we provide an unprecedented example of germylene-type reactivity of the Ge(100) surface provoked by adsorption of a dense monolayer of TBIC. Infrared spectroscopy experiments under ultra-high vacuum conditions were conducted together with density functional theory calculations. The suggested structure of the product resembles a germa-ketenimine molecule. Overall, our study expands the knowledge on the reactivity of the Ge(100) surface that parallels that of molecular group 14 compounds. [1] B. Shong, K.T. Wong, S.F.
